A hand-held electronic device with a keyboard optimized for use with the thumbs is disclosed. In order to operate within the limited space available on a hand-held electronic device, the present invention optimizes the placement and shape of the keys, preferably using keys that are oval or oblong in shape, and that are preferably placed at angles designed to facilitate thumb-typing. The angles at which keys on either side of the keyboard are placed is complimentary.
